Early radical cystectomy for a high-grade tumor invading the lamina propria (T1) remains controversial. In 1997, we cannot identify accurately which of these high-risk tumors will progress to muscle-invasive disease and metastases. In the near future, urologists may be able to use the presence of genetic alterations, such as p53 mutations, to help make therapeutic decisions. Previous reports on superficial bladder cancer treated with intravesical bacillus Calmette-Guérin immunotherapy have demonstrated a decrease in recurrence and progression. Unfortunately, there is no reliable method to predict which patients with a high-grade T1 tumor will fail to respond to intravesical therapy. Failure of intravesical therapy to control these aggressive tumors is associated with a significant rate of pathological upstaging and metastases. Radical cystectomy will cure a high percentage of these T1 tumors with acceptable morbidity and low mortality. In an era of nerve-sparing cystectomy and orthotopic neobladder reconstruction, early radical cystectomy is an alternative that should be discussed with the patient before instituting intravesical therapy.
对于侵犯固有层的高级别肿瘤(T1期)早期行根治性膀胱切除术仍存在争议。1997年时,我们无法准确识别这些高危肿瘤中哪些会进展为肌层浸润性疾病和发生转移。在不久的将来,泌尿外科医生或许能够利用基因改变的存在,如p53突变,来辅助做出治疗决策。既往关于采用卡介苗膀胱内免疫疗法治疗浅表性膀胱癌的报告显示复发率和进展率有所降低。遗憾的是,尚无可靠方法预测哪些高级别T1期肿瘤患者对膀胱内治疗无反应。膀胱内治疗无法控制这些侵袭性肿瘤与显著的病理分期升级和转移率相关。根治性膀胱切除术能治愈很大比例的这些T1期肿瘤,且发病率可接受、死亡率低。在保留神经的膀胱切除术和原位新膀胱重建的时代,早期根治性膀胱切除术是一种可供选择的方案,在开展膀胱内治疗前应与患者进行讨论。
